HEATER.

SPECIFICATION forming part of Letters Patent No. 756,721, dated April 5, 1904.

Application filed November 20, 1903; Serial No. 181,949. (No model.)

To all whom it may concern:

Be it known that I, .Laces SILVERBERG, a citizen of the United States of America, residing at Pittsburg, in the county of Allegheny vt`0 provide means .for increasing the amount of heat derived from a stove of given dimensions, accomplished by increasing the burner capacity of the stove without increasing the other dimensions.

A still further object of the present invention is to provide a stove adapted for use in the same manner as an ordinary heating-stove, but which in its principle is also adapted for use for mounting on a gas-jet, if so desired.

Briefly described, the invention comprises a shell or casing and a supporting-base therefor, and within the shell or casing is arranged a circular or cylindrical receptacle into which the gas is f'ed from a source of supply and which receptacle is perforated to permit the gas to escape to the point of ignition. On the exterior surface of this receptacle is secured a covering of asbestos to throw 0H' the heat of the burning fuel in a manner well known.` A cluster of the receptacles mayY be arranged within the shell or casing, if so desired, all fed from a common source of supply.v

' The construction in detail will be hereinafter more specifically described and then particularly claimed, and in describing the inven) tion in detail reference will be had tothe accompanying drawings, forming a part of this application, and wherein like numerals of reference will be employed to designate like parts throughout the different views ofthe drawings, in which Figure 1 is a central vertical sectional view of a heating-stove constructed in accordance with my invention. Fig. 2 is a similar view thereof with the shell or casing removed. Fig. 3 is a top plan view with the shell or casing removed. Fig. 4 is a plan view, partly broken away and with the casing or shell removed and the central receptacle in horizontal section. Fig. 5 is a-central vertical sectional view of a modified formof construction. Fig. 6 is a top plan View of another modified form of construction. Fig. 7 is a central vertical sectional view of a part of the interior receptacle in modified construction.

As shown in Figs. 1 to 4 of the drawings, to construct a heating-stove in accordance with my invention I provide a suitable supporting-base 1, which may or may not be provided with supporting-feet 2, as shown. On this base is suitably mounted a cylindrical receptacle which acts as the burner, and in the present construction I have shown a convenient method of fastening, which comprises a screw 3, carried by the base 1, the base 4 of the cylindrical burner 5 being provided with a threaded aperture to receive the screw 3, and thus hold the burner in position. It will of course be evident that equivalent fastening means could be employed without departing from the spirit of the invention. I prefer'to make the cylindrical burner corrugated, as shown, the orifices .6 provided circumferentially in the burner being preferably made in the depressions of theJ corrugations, the exterior of theburner having a covering of non-y combustible material 7, usually of asbestos. The burner may be formed with integral upright walls and bottom, with the top 8 provided with a depending annular flange 8, which is secured on'the upper en d, or both top and, bottom may be made separate from the cylindrical receptacle or burner and` suit- A supply pipe 9 is tapped into the burner near the base, being bly securedl thereto.

provided with any desired form of mixer10-95 base,"being s'o"placed as fit just inside the walls of the casing o r shell. vThis casing or shell isprovided with perforations 15, through which the heated air escapes and which also brings the burning fuel partly into view to vadd to the appearance of the stove. The casingr shell may or may not be provided with,

the removable cap-piece 16 in its-top.

In the operation of the device just described lthe mixed air and gas is discharged into lthe cylindrical burner vandv escapes through the openings 6,Where it-s ignited, the iiames er1- tirely surrounding or enveloping the burner,

materially increasing the burner-surface over that of an ordinaryburner-back. I may provide the burner with a top 8', having an overhanging flange 9', forming a deflecting hood, as vseen in Fig. 7, against which the flames would strike so as to deiiect the vsamel outwardly. K l

In Fig. 5 I'show the adaptation ofthe same principle to a heater to be attached direct to a gas-jet leading out from 4the Wall or other point.` In this construction the base 17 has a' mixer 18 tted centrally therein; which mixer receives the tip of the gas-jet 19.l 'Ihe mixer carries a screw or threaded stud 20'0nto which the burner 21 is secured, the burner being of the same construction as shown in Figs. l to 4:.: The base'l? is provided With an annular iiange 22, within which the shell or casing 23 fits, the said shell or casing being provided With a suitable 'cover 24C and being preferably provided with perforations4 25.

In Fig. 6 I show' th'e adaptation of thel same principle to a vstove having a cluster of burn-I ers, the she'll or casing 26 inclosing all the A. M. WILSON',

burners A27, which arearranged inany desired form' in their cluster, the supply-pipe leading,

preferably, to the central' burnerjof theclustively small space, as will be readily apparent.

With this construction of burner itis tobe observed that the gas -being discharged into f the circular burner' and fed out. therefrom all around 4the burner all of the gas' is utilized,

thus materially increasing the heat-thrown oli' f' bythe heater.

While 1 haveV herein shown and destra@a., the invention indetail as it has been-practiced..

by Ine, yet itwillbe evidentthat .various slight changes I nay be Amade in the details Without departing' from the kgeneralrsp' itfot the invention. e Having fully' described my invention what I claim as new, and desire to secure byLetters In a heater of the type described, acorrun gated cylindrical burner 'providedvwith perforations and having a covering of .n0n-com bustible material,an annular depending ange carried by said burner at its upper end forming a deector, and a supply-pipe communieating with the burner.

In testimony whereof I ax my signature in the presence of two witnesses.
